There seems to be a limit to number of items that can be included in c() function in R (100 items). Is there any way to evade this limitation? Thanks in advance.

`dput(do.call(c, as.list(rep(letters, length.out=1e3))))` works fine – baptiste Jan 02 '13 at 00:36

1Dup. And -1 for minimal effort. Search on: [r] maximum length vector: http://stackoverflow.com/questions/10640836/max-length-for-a-vector-in-r – IRTFM Jan 02 '13 at 01:24

There is a limit, but it is a limit of vector length, not a limitation of c:
length(eval(call('c', 1:(2^31-1))))
## [1] 2147483647
length(eval(call('c', 1:(2^31))))
## Error in 1:(2^31) : result would be too long a vector

I think R 3.0 (or whatever version number they end up using) overcomes the 2^31 - 1 index limit – Róisín Grannell Jan 02 '13 at 02:43

I'm going to need more memory. `1:(2^31-1)` takes 25% of my RAM, and `1:(2^31-1)+.5` takes 75%. – Matthew Lundberg Jan 02 '13 at 02:50
